I for one do not like the .264 Winchester mag. My experience with it goes back to 1966. I found that the ctd. is badly overbore capacity, and burns out barrels vary fast. The throat is gone in 150 rounds and the barrel has had it in 500 rounds.

I think the 6.5x55mm, to be one of the worlds best ctgs. If you just want something to be different then look to the 6.5/284 a fine ctg with a vary good reputation for long range accuracy.
